摘要
2021年在陕西渭南地区以玉米西蒙185为供试材料,共设置8个播期,研究播期对西蒙185果穗性状及产量的影响,确定西蒙185的最佳播期,旨在为西蒙185的高产栽培及进一步的推广应用提供理论支撑。研究发现,随着播种时间的推迟,玉米产量呈现出先上升后下降的趋势,在5月8日播种的玉米产量最高,达到12204.00 kg/hm^(2)。经回归分析发现最佳播期在5月8日~18日之间。
In 2021,using Ximeng 185 as the test material,the influence of different sowing dates on the characteristics and yield of Ximeng 185 was investigated using 8 different sowing dates.The aim was to find the most suitable sowing date for Ximeng 185 in Weinan,to provide a theoretic support for the high-yield cultivation,large-scale popularization and application.The results showed that with the postponement of the sowing date,the yield of corn increased at first and then decreased,and the corn yield reached the maximum of 12204.00 kg/hm^(2) on May 8.Based on the regression equation analysis,the most suitable sowing date is between May 8th and May 18th.
